Histone Lysine acetyltransferase
The acetylation of histones is mediated by Lysine acetyltransferases catalyze the transfer of acetyl group from acetyl-CoA to the ε-amino group of specific lysine residues. This neutralizes the positive charge of the lysines and alters the histone-DNA interaction. There are total twelve unique proteins reported to have the histone acetyltransferases activity in rats.
